Here's the 'official' solution, with photo: ".. Apparently the IBM Travelstar creates an unusually high magnetic field for a 4200 RPM hard drive, which interferes with the PowerBook's "sleep switch" located inside the lower body housing adjacent to the Delete key and right above to the hard drive. When you close the PowerBook cover while the PowerBook is on, it will not awaken from sleep mode, if you close it after shutting down, it will not start up. You will hear an "electronic clicking" sound when you press the power button. There has been a lot of discussion on this subject on various tech sites. People have also reported that a small weak "refrigerator magnet" placed for a second on the case next to the delete key "resets" the sleep switch, something I don't think an owner should have to do!
The permanent solution is actually simple, place a .04mm thick sheet of a non ferrous metal like brass between the HD and where the sleep switch is in the body of the PowerBook.I purchased a small piece of .2mm (1/64th") thick sheet of polished brass and then cut it in half to the right width to fit between the screws inside the hard drive caddy (see photo below). We needed to use a double thickness of the brass, to block the magnetic field created by the 40GB drive. Larger drives may need even more brass.."
